A handful of friends, who have uncontrollable TDS.
You could say I am rabidly pro-Trump.
That being said, I can tell you I would never, ever instigate a propane filled in your face attack on someone I knew to be a liberal, be it in person or online.
Yet, it seems many, if not most lefties have no difficulty doing that.
That, coupled with what I believe to be completely irrational political positions, leads me to honestly conclude that liberalism is, indeed, a mental disorder.
